Paints for industrial and household use are commonly marketed in cans ofvarious sizes, usually cylindrical cans. The paint manufacturer receivesthe cans from a supplier, and the storage and shipping of the empty canspresents serious problems owing to the amount of space they take up,thus raising the cost which is passed on to the consumer.

It is an object of the present invention to provide an altemativecontainer construction which largely overcomes these problems.

Basically, the invention provides a container which comprises first andsecond separately storable components adapted to be assembled togetherfor use, each component being collapsible into a substantially flatcondition so as to minimize the space it occupies during transport andstorage prior to its being used.

A container according to the invention basically comprises a cartonhaving a base with four upstanding walls defining a rectangular topopening; a rectangular lid adapted to close the top opening, the lidproviding a dispensing opening, and a depending skirt positioned toextend inside said top opening; means for securing the lid to the cartonto close the top opening; a closure for said dispensing opening; and aflexible bag of a material which is impermeable to the liquid to becarried, the bag having an opening at one end which is sealed around itsedge to said depending skirt.

One embodiment of the invention will now be described by way of examplewith reference to the accompanying drawings, in which:

FIG. 1 is a general perspective view of an assembled paint containeraccording to the invention;

FIG. 1A shows a detail of FIG. 1 with the closure removed;

FIG. 2 is an enlarged section on line 22 in FIG. 1;

FIG. 3 is an enlarged section on line 33 in FIG. 1; and

FIG. 4 is an exploded perspective view showing the elements of thecontainer.

Referring first to FIG. '4, the elements of the container include acarton 10, a bag assembly 11 with closure 12, and a handle 13.

The carton consists of a tubular blank (shown in the flat collapsedcondition) having four panels, two of which are shown at 14 and 15,defining wall portions, and four extension flaps l6, l7, 18, 19,defining a base portion. The blank may suitably be of corrugatedcardboard. As illustrated in FIG. 1, the blank is erectable into acarton having a base and four upstanding walls defining at the top arectangular opening, the opening being closed by a rectangular lid 20.Near the top edge of the panel 15 is a short rectangular. slot 21, asimilar slot being provided near the top edge of the opposite panel.This slot may be provided on all four panels if desired.

The bag assembly 11 comprises a flexible bag 22 of polyethylene or likematerial which is impermeable to the paint to be carried. The bag hastwo generally rectangular panels 23 meeting at a lower edge 24, and twogenerally triangular panels 25 which are gussetted to permit the bag tobe folded into a flat condition against the lid 20. When the bag isfilled it is distended into a cubelike shape and substantially fills thecarton. The lid is a rigid one-piece moulding of thermoplastic materialhaving a ribbed upper surface as shown in FIG. 1. Adjacent to one cornerof the upper surface is a rectangular dispensing opening 26, bounded bya beaded rim 27; the closure 12, which is of the same material as thelid, is formed at its edge with a channel 28 shaped to fit on to the rim27 and to engage it resiliently whereby to fasten the closure over thedispensing opening. A hand tab 38 is integrally moulded with the closureto facilitate its removal.

The lid 20 is formed with an integral depending skirt 29 which extendsinside the top opening of the carton 10, as shown inFIGS. 2 and 3, theskirt lying immediately adjacent to the inner surfaces of the fourcarton walls. The lid 20 is also formed with a peripheral dependingflange 30 lying parallel to the skirt 29 and defining therewith achannel into which the upper edges of the carton walls fit. The bag 22as a rectangular opening at its upper end, defined by the edges of thefour panels 23, 25, and the edges of the opening are heat sealed orotherwise joined to skirt 29 to form a continuous painttight joint.

On each of two opposite side portions of the skirt 29 is an outwardlyprojecting ledge 31 with integral triangular gussets 32 which form arigid projection of generally wedged shape. The projection is adapted toengage into a respective slot 21 of the carton wall, the wedge formationpermitting the lid to be placed on the carton easily, to close the topopening, but preventing its removal.

The handle 13 consists of a rod which is bent to provide a crosspiece 33extending between two U-shaped portions 34 and two side portions 35, theside portions terminating in respective axially aligned, inwardly turnedportions 36, which engage retaining means 37 in the flange 30. Theinwardly turned portions may be extended to engage beneath the ledges31. This handle formation enables the container to be supported from arung of a ladder, or the like during use.

It will be appreciated that a stock of containers prior to being filled,may be stored and shipped easily since the amount of storage andshipping space required is relatively small. The containers wouldnormally be shipped and stored in three lots: first, the carton blankswould be stacked in flat, collapsed condition; second, the bagassemblies would be stacked in flat, collapsed condition, the bag ofeach assembly being folded into the well defined on the underside of thelid by the skirt 29; third, the handles would be stored separately. Theerection of the containers ready for filling by the manufacturerrequires a minimum of labor, it being necessary only to erect thecarton, unfold the bag, place the lid onto the carton, and fix thehandle in place.

What I claim as my invention is:

l. A container for liquids comprising a carton having a base with fourupstanding walls defining a rectangular top opening; said cartoncomprising a one-piece blank which is collapsible into a flat condition;a rectangular lid adapted to close the top opening; said lid being aone-piece rigid moulding of thermoplastics material, the lid providing adispensing opening positioned adjacent to one corner of the lid, and adepending skirt positioned to extend inside said top opening, the lidbeing formed with an integral depending peripheral flange lying parallelto the depending skirt and defining therewith a channel adapted toreceive the ends of said upstanding walls; means for securing the lid tothe carton to close the top opening; a closure for said dispensingopening; a foldable flexible bag of a material which is impermeable tothe liquid to be carried, the bag having an opening at one end which issealed around its edge to said depending skirt; a handle comprising arod bent to form a cross portion extending between two side portions,each side portion terminating in an inwardly turned end, said ends beingaligned with one another; and the container further including means forconnecting said inwardly turned ends to said depending peripheralflange.
